【摘要】 以信息电器为代表的嵌入式应用系统真正拉开了嵌入式系统大发展的序幕,它必将进一步推动IT产业的发展,给人类的生产、生活带来深远的影响,嵌入式系统自诞生以来经历了一个从无到有、从弱到强、从少到多的发展过程而生产嵌入式系统的开发工具却越来越落后于实际的需要,并逐步成为嵌入式系统进一步发展的瓶颈。 应用平台开发战略正是在这样的背景下诞生的,它顺应了历史发展的潮流,也必将会得到更大的发展和应用。嵌入式系统是软件和硬件的综合体,软件又包括嵌入式操作系统和上层应用程序,导致嵌入式系统开发周期长,难度大、效率低、出错率高、成本也居高不下。嵌入式系统开发分为两个阶段,即嵌入式平台的开发阶段和针对某个应用的应用程序开发阶段,开发人员或企业不需要向以往一样对产品的软件和硬件从零开始开发,可以直接在现成的嵌入式平台上进行产品的开发,大大缩短了开发周期,及时地推出自己的产品,增加了产品的市场竞争力。 本论文的主题就是针对测控领域研究设计了一个嵌入式平台,该平台主要集成了数据采集,液晶显示,无线射频数据传输的功能。 论文的第一部分主要介绍课题研究背景和意义,嵌入式系统基础知识,包括嵌入式系统的分类,应用领域,现状和发展前景以及论文的组织结构。第二部分主要对和系统相关的技术进行研究,包括嵌入式系统的总体结构,一般设计方法,嵌入式硬件平台和实时操作系统的选择原则,ARM处理器,集成开发环境ADS1.2。第三部分主要设计了应用平台总体方案,主要包括前期数据采集和后期数据处理两个部分,后期数据处理部分主要实现液晶显示,无线数据传输两个功能。第四部分主要是对应用平台的硬件设计,详细介绍了主要单元电路。第五部分主要是对应用平台的软件设计,包括启动加载程序BootLoader,操作系统uC/OS-Ⅱ在S3C44BOX上的移植和串口通信程序。更多还原

【Abstract】 Now, the embedded application system, represented by information appliance, is leading embedded system to booming development. It will make the information technology industry get more development, and bringfar-reaching influence to people’s production and life. The embedded system is coming through a developing course from simple to complex. But now the devising tools of embedded system is still far behind hand to thepractical need, and this is more and more becoming the obstacle in the developing road of embedded system.On this background, developing stratagem based on platform has been put forward, and is getting quick development and application. Embedded system is the colligation of hardware and software, software contain operation system and above application program, it lead that the develop period is very long, and difficulty is very strong. Now the developing of embedded system contain two parts, universal embedded system and above application program development. Researcher or company don’t neeed develop entire hardware and software of embedded system, can develop the embedded system on the basic of developed system.This paper assumes a development project about the application platform of embedded system which applied in measure and control system, which mainly realize the function of data collection, LCD display, wireless data transmission. The first part of this paper mainly introduce background and sense of research, basic knowledge of embedded system and so on. The second part of this paper mainly research related theory knowledge about embedded system, which contain the structure of embedded system, designing method , embedded operation system and develop entironment. Finally, this paper mainly introduce the design of hardware and software.更多还原
